The effect of inbreeding on natural selection in a seed-feeding beetle Article

The effect of inbreeding on natural selection in a seed-feeding beetle - Article Example The objective of the study is to understand whether offspring survival related to egg size is affected by inbreeding or not. To conduct the experiment beetle population was collected from Acacia gregii and bred in the laboratory for almost 12 generation before experimentation. Seed pods from both A. greggii and P.florida trees were used to fulfill the seeds requirement in the experiment and the seeds of the individual trees were thoroughly mixed to control seed coat variation among the seeds. Following the experimental design outbred females were mated with one sibling or non-sibling outbred male beetle after which the female laid their eggs on P.florida to record survival of all the offspring while A.greggii was used for rearing owing to the high rate of larval survival. These first generation adults when emerged from the seeds were used to create a second generation of both inbred and outbred offspring. The beetle pair was put in Petri dishes containing 20 seeds of P.florida and only one larva per seed was allowed to develop inside a chamber controlled at a temperature of 29-30 degrees. In the experimen t, 2-3 eggs were measured per Petri dish using a dissecting scope and finally 460 eggs from females mated to sibling males and 512 eggs from females mated to non-sibling males were collected. To illustrate the relation between the offspring survival and the size of the egg GAM model and linear probability models were used. The conclusive results showed that egg size did not differ much between females that were inbred and out bred; however, inbreeding vastly affected the survival rate. Eggs resulting from outbreeding survived more than those that were inbred. The values for egg to adult survival 0.66 in case of outbred offspring but a reduction of about 29.5% was seen in case of inbred ones. Linear probability model revealed that larva from larger eggs survived more than those emerging from smaller ones. It was evident from the logistic regression

Energy Security For India Environmental Sciences Essay

Energy Security For India Environmental Sciences Essay India stands on the verge of achieving its dream of being a world power today as her economy races ahead seemingly unstoppable. Though we have been able to achieve food security to feed our burgeoning population, the hunger of our economy is yet to be satiated. A growing economy demands energy an uninterrupted supply of energy. Today in this world of competing economies, the conflict of securing means of energy within the rising economy of the world has the potential of being the spark needed to ignite a new world war. No country produces enough energy in the required forms to satisfy its energy needs, thus we are facing the possibility of conflict as each nation tries to nudge out the other from the energy producing areas of the world in order to ensure a continuous supply of energy. India today faces this formidable challenge of not only meeting her energy needs but also providing adequate varied energy of desired quality to the users at a reasonable cost in a sustainable manner. With an economic growth of 8-10 percent sought after, the quality quantity of energy required is only going to increase exponentially. 4. As India looks to the future and aims to secure her rightful place in the emerging new world order, it is imperative for the nation to understand and plan for a secure energy environment to cater for sustained economic growth. Energy security will play a pivotal role around which Indias rapid progress and development may be sustained in the foreseeable future. It is incumbent on each one of us to have sufficient knowledge of the complexities of this issue which will play such an important role in our day to day lives in the years to come. 7. There are certain terms and definitions which are peculiar to the concept of Energy Security. The term Energy Security itself is yet to get a single definition and various interpretations of this term abound. The following few terms relevant to the syndicate research effort are clarified in the subsequent paragraphs. 8. Energy Security. Energy security can be defined as The continuous availability of energy in varied forms in sufficient quantities at reasonable price This definition of energy security implies the following:- (a) Energy should be provided to all citizens and if this is not possible, then it is not a sustainable situation for a country. (b) Energy security requires that the lifeline energy needs of the nation are met in full. Lifeline energy is the basic necessity of a person to live. (c) Demand of energy backed by the ability to pay by whole strata of society should be fully met. (d) Safe and convenient energy is desirable as use of traditional fuels such as wood or cow dung cakes lead to indoor air pollution which has adverse impact on the health of women and children. (e) Energy is required in different forms to meet different needs. Energy in one form cannot be easily substituted by other forms. If we try this substitution, it would cost a lot of money and quality of the end product also goes down. For example, using kerosene for lighting houses instead of electricity. (f) Energy should be available at all times. An interruption in this chain imposes high cost on the economy. (g) To ensure energy security at all times, shocks and disruptions should be anticipated. A country should have the ability to absorb these shocks or disruptions. 9. The Minister of Petroleum and Natural Gas, Shri M.M.Deora, delivered a speech in the Shell Distinguished Lectures Series at Rice University, in Houston, Texas, U.S.A. on 31 March 2006. During this speech, he defined energy security in the Indian context as the assurance of energy supply to all Indian citizens at affordable cost at all times with a prescribed confidence level considering shocks and disruptions that can be expected.  [2]   10. In our context, the above definition could be further modified. In India, energy security can be defined as follows We are energy secure when we can supply lifeline energy to all our citizens irrespective of their ability to pay for it as well as meet their effective demand for safe and convenient energy to satisfy their various needs at competitive prices, at all times and with prescribed confidence level considering shocks and disruptions that can be reasonably expected.  [3]   11. Relevant Terminologies. (a) Energy Independence. The condition in which a country is not beholden to foreign nations or fluctuations of the market in meeting its energy needs. Most countries would like to have a greater degree of energy independence. (b) Energy Interdependence. The idea that oil producers and consumers are mutually dependent on one another. An appreciation of interdependence is an important component in the evolving conception of energy security. (c) Resilience. Resilience as the term itself implies, refers to a security margin that would allow a country to absorb any minor shocks to its energy supply and facilitate recovery after disruptions. Global Energy Situation 12. For the first time since 1998, global primary energy consumption fell in 2009, but like the broader economic downturn, changes varied greatly across regions. With consumption falling, energy prices declined in 2009, though again the pattern varied by fuel. Oil prices began the year below $40 per barrel, and increased steadily during the year as Oil Producing and Exporting Countries (OPEC) production cuts were greater than the decline in consumption. Natural gas in competitive markets fell sharply and remained weak through most of the year due to falling consumption, continued development of unconventional resources in the US and rising Liquefied Natural Gas (LNG) supply. Coal prices also fell and then started to recover, while displaying regional variety. The recession and now, hopefully, the recovery, has taught us how interlinked the world really is.  [4]   13. Oil. Global oil consumption declined by 1.2 million barrels per day (b/d), or 1.7percent, the largest decline since 1982. China, India and Middle Eastern countries accounted for all of the non- Organisation for Economic Cooperation and Development (OECD) growth. Global oil production dropped even more rapidly than consumption, falling by 2 million b/d, or 2.6 percent, the largest drop, again, since 1982. OPEC production cuts implemented late in 2008 were maintained throughout 2009, resulting in a decline of 2.5 million b/d, or 7.3 percent. Every OPEC member participating in the production-cutting agreement reduced output in 2009. OPECs Middle Eastern members accounted for nearly 75 percent of the overall reductions. Oil production outside OPEC grew by 0.9 percent or 450,000b/d. Non-OECD capacity surpassed OECD capacity for the first time. The Asia-Pacific region accounted for more than 80 percent of the global growth, largely due to increases in India (+19.5percent, or 580,000b/d ) and China (+10.5percent, or 820,000b/d). Global crude runs fell along with oil consumption, declining by 1.5 million b/d, or 2 percent. The proved oil resources and oil consumption by the region are enumerated in the map and graph :- 14. Natural Gas. Globally, natural gas was the fuel that experienced the most rapid decline in consumption, falling by 2.1 percent, the largest decline on record. Consumption declined in all regions except the Middle East and Asia Pacific. Russia had the worlds largest decline (in volumetric terms), with consumption falling by 6.1percent. OECD consumption fell by 3.1 percent, the largest decline since 1982; the decline in the US was a relatively modest 1.5 percent, as weak prices improved gass competitive standing against other fuels. Iran saw the worlds largest volumetric consumption growth, while Indian consumption growth of 25.9 percent was the highest among major countries in percentage terms. Global gas production declined for the first time on record. Production fell sharply in Russia (-12.1 percent) and Turkmenistan (-44.8 percent), driven by declining consumption in Russia and much of the rest of Europe and the availability in Europe of competitively priced liquefied natura l gas (LNG).  [5]  Continued expansion of unconventional supplies allowed the US to record the worlds largest increase in production for the third consecutive year, surpassing Russia as the worlds largest producer. Production in the Middle East and Asia Pacific also increased, driven by growth in Iran, Qatar, India and China. The proved natural gas reserves of the world are shown below:- 15. Coal. World coal consumption was essentially flat in 2009, the weakest year since 1999. For the first time since 2002 , coal was not the fastest growing fuel in the world. The OECD and the former Soviet Union experienced the steepest decline on record, while the growth elsewhere was near average, largely due to above average growth in China, which accounted for 46.9 percent of global coal consumption.  [6]  Today coal accounts for 23.3 percent of the worlds energy demands and this figure is likely to increase by 60 percent by 2030. 16. Nuclear Fuel. Global nuclear power generation declined by 1.3 percent a third consecutive annual decline. Lower output in Europe and Eurasia as well as North America,outweighed increases in Asia Pacific.  [7]  Nuclear fuel contributes to only 6.8 percent of global energy requirements; however, this is likely to see a sharp rise by 2030. 17. Hydroelectricity. Hydroelectricity output grew by a below average 1.5 percent which was non the less sufficient to make it the worlds most rapidly growing major fuel in 2009. Growth was led by China Brazil and the USA. USAs Energy Policies and their Impact on India 18. The first decade of the new millennium has seen the energy interests of India and the United States of America intertwine like never before. The issues of continuing reliance on fossil fuels, increasing dependence on imports to satiate energy hunger and the need to address the issue of climate change has further enhanced the cooperation between the two countries. The United States of America has enunciated the following as the strategic goals and the measures to achieve them, for its energy policy:- (a) Energy Diversity. Increase energy options and reduce dependence on oil, thereby reducing vulnerability to disruption. The strategies to reach this goal are as follows:- (i) Reduce dependence on energy imports, particularly oil in the transportation sector, by developing and effectively deploying technologies to increase fuel efficiency and enable the substitution of alternatives such as bio fuels, electricity, and hydrogen. (ii) Collaborate globally with governments and scientists to expedite the development and deployment of unconventional energy resources, such as bio fuels, that can substitute for oil and natural gas. (iii) Collaborate globally with governments and scientists to expedite the development and deployment of nuclear power which can substitute for oil and natural gas. (iv) Ensure adequate crude and regional home heating oil supplies during emergency shortages by maintaining the operational readiness of the Strategic Petroleum Reserve and North East Home Heating Oil Reserve. (v) Ensure an expanding supply of domestic energy for the American public by promoting the construction of an Alaska Natural Gas Pipeline and the environmentally responsible development of the Outer Continental Shelf and the Artic National Wildlife Refuge. (b) Environmental Impacts and Energy Strategies to Reach this Goal. (i) Support the creation of new nuclear generation capacity to produce carbon-free electricity in the near term (2015); complete a permanent repository for nuclear waste at Yucca Mountain by 2017; and, develop next generation advanced reactor and fuel cycle technologies for deployment in the long term (2025) for both electricity and hydrogen production. (ii) Advance clean coal technology through public-private partnerships for continued electricity generation from the countrys extensive coal resources, ultimately resulting in near-zero atmospheric emissions power plants. (iii) Support research and development efforts to reduce the costs of renewable energy technologies and accelerate the large-scale use of carbon-free electricity sources. (iv) Develop technologies to reduce vehicle emissions by improving efficiency and greatly expanding the use of clean fuels, while maintaining vehicle safety, performance, and cost characteristics. (c) Energy Infrastructure and Strategies to Reach this Goal. (i) Develop advanced wires and coils to increase the capacity, efficiency, and reliability of the electricity system. (ii) Advance real-time visualization and control tools to improve the reliability and efficiency of the Nations electricity delivery system by increasing the utilization of transmission and distribution assets. (iii) Integrate advanced technologies, including distributed generation, storage, and load management on distribution utility feeders to improve the efficiency and reliability of constrained sections of the electricity grid. (d) Energy Productivity and Strategies To Reach This Goal. (i) Support enhancements to existing energy markets that will help stimulate private investment in more efficient and economically productive end-use technologies. (ii) Develop integrated building technologies and formulate appliance standards to significantly increase the energy efficiency of residential and commercial buildings. (iii) Partner with energy-intensive industries to develop technologies that enable more efficient use of energy in their industrial processes. (iv) Develop technologies that enable cars and trucks to be fuel efficient, while remaining cost and performance competitive. 19. Impact on India. (a) Development and Deployment of Renewable Energy Technologies. The domain of renewable energy offers tremendous opportunities for strengthening Indo-US relations. While US companies have already invested heavily in the Indian market, especially in the field of solar energy, Indias own Suzlon Energy Cooperation has emerged as the worlds fifth largest supplier of wind turbines and the US forms a hub for its operations. Thus this two way exchange benefits both countries. (b) Promoting Energy Efficiency and Power Sector Reforms. The Unites States of America had set this as a major target for its energy security goals in the coming future. At the same time,the Indian energy security policy also aims at achieving better energy efficiency across all sectors. The USAID collaboration with the Government of India has already brought out the formulation of the Bureau of Energy Efficiency (BEE) in India which has set the energy efficiency standards for various appliances in the country. As the US take further strides in this field, India too can benefit from its experience. (c) Civil Nuclear Deal. The signing of the civil nuclear deal has opened up new opportunities for the Indian nuclear industry. With the technology now available as a result of the deal, India would be able to increase the share of nuclear energy in its energy basket form a meagre three percent now to nearly eight percent by 2030. (d) Clean Technologies in the Field of Non Renewable Resources. With the world still dependent on non renewable sources such as oil and coal, the need of the hour is to develop technologies which can assist in better utilisation of the fuel in a more energy efficient and environmentally friendly manner. The two countries can collaborate in this field to develop these technologies. Chinas Energy Policies and thier Impact on India 20. China become a net importer of oil in 1993 and since then embarked on wide ranging changes in its energy policies in order to ensure a continuous supply of energy to fuel its phenomenal growth. With its entry into the global oil bazaar as a major importer, China quickly learned the hazards of relying solely on purchase policies in the open markets. The more aggressive recent foreign investments of its state owned enterprises, notably China National Petroleum Corporation (CNPC) and China National Offshore Oil Company (CNOOC), stem directly from a May 1997 policy paper in which former Premier Li Peng blessed Chinese involvement in the exploration and development of international oil and gas resources .He also tied such projects specifically to the objective of stable, long-term supplies of oil and gas. The Chinese governments energy policies are dominated by the countrys growing demand for oil and its reliance on oil imports. The National Development and Reform Commission (NDRC) is the primary policymaking and regulatory authority in the energy sector, while four other ministries oversee various components of the countrys oil policy. The government launched the National Energy Administration (NEA) in July 2008 in order to act as the key energy regulator for the country .The policy focused on the following areas: (a) Self sufficiency. (b) Encouraging the diversity of energy structure and imports. (c) Improve energy efficiency and adjusting economic structure. (d) Energy conservation. 21. Impact on India. (a) Chinas String of Pearls strategy is well known as a means of encircling India; however the origin of this strategy lay in securing her energy needs. These pearls extend from the coast of mainland China through the littorals of the South China Sea, the Strait of Malacca, across the Indian Ocean, and onto the littorals of the Arabian Sea and Persian Gulf. China is building strategic relationships and developing naval forward presence along the SLOCs that connect China to the Middle East. The list of pearls include the following: upgraded military facilities in Hainan Island, upgraded airstrip on Woody Island located in the Paracel archipelago about 300 nautical miles east of Vietnam, container shipping facility in Chittagong, Bangladesh, construction of a deep water port in Sittwe, Burma, construction of navy base in Gwadar, Pakistan, pipeline through Islamabad and over Karakoram Highway to Kashgar in Xinjiang province that would transport fuel to China itself, intelligence gatheri ng facilities on islands in the Bay of Bengal near the Malacca Strait and construction of Hambantota port in Sri Lanka. (b) Loan for Oil. China is taking advantage of the economic downturn to step up its global acquisitions and financing of projects. One of the financing strategies is to secure long-term deals is Chinas bilateral loan-for-oil deals with several countries. These loans amount to about $50 billion or 70 percent of the total investments by the 3 major NOCs since 2008 according to industry sources. While several resource-rich countries have been strapped for cash during the credit crunch of 2008-09, China can use its vast foreign exchange reserves, estimated at $2 trillion, to help leverage such investments. China finalized loan for oil deals recently with Russia, Brazil, Venezuela, Kazakhstan, Ecuador and reportedly agreed to a loan of $3 billion to Turkmenistan to assist in developing the South Iolotan gas field project to feed the Central Asia Gas Pipeline. China agreed to loan Russian companies, Rosneft and Transneft $25 billlion to finance the East Siberia Pacific Ocean oil pipeline i n exchange for 300,000 bbl/d of oil shipments. The Chinese Development Bank (CDB) also agreed to loan Petrobras of Brazil $10 billion so that Sinopec can access 200,000 bbl/d of oil for export to China. The loan to Venezuela stands at $4 billion to finance various projects increasing oil exports to China almost three-fold to 1 million bbl/d by 2015. CNPC and the China Export-Import Bank intend to lend Kazakhstan $5 billion each in two loans allowing CNPC a much larger role in the upstream oil development in the Central Asian country, following the companys acquisition of Petro Kazakhstan in 2005. (c) Acquisitions in Africa. Many in the oil industry agree that the most pragmatic acquisition strategy would be to look for good exploration blocks. But this is predicated on having a corporate team capable of evaluating possible exploration acreages in the world, which the big international oil companies have. Unfortunately, however, most of the Indian oil companies, unlike the Chinese companies, do not have a comprehensive set-up or database to follow this strategy, with the result that India ends up acquiring blocks that are in the very high risk category. Neither are the exploration blocks acquired in the bidding round examined in depth due to shortage of time available thanks to lack of adequate research of the area. Although Indian oil companies have notched up some successes over the last few years in buying equity stakes in foreign oil and gas blocks, the most notable being the Sakhalin-1 (offshore) project in Russia and the Greater Nile project in Sudan where the Chinese al so have a major interest, they have failed in many more or managed to acquire marginal stakes in others. For instance, India lost a bid to acquire Royal Dutch/Shells 50 per cent interest in Block 18 offshore Angola, which includes the Greater Plutonia development, with reserves of one billion barrels, after the Chinese government offered the Angolan government a 17-year, $2 billion loan at a low (1.5 per cent) interest rate along with the offer to build hospitals, and electronics manufacturing factories.  [8]  The Indian government was also prepared to support ONGC by offering $200 million to help build a railway, but this was dwarfed by the Chinese package.

title of website or page? YOUR HEALTH IS YOUR WEALTH Research has shown that there is a direct correlation with unequal societies and poor heatlh. The findings suggest that determining health in a society, is dependent on how wealth is distributed. Past data has indicated that there is better life expectancy where their is more equal distribution of income. The most unequal places have the highest death rates, with a small decline Policies that address equal income distribution have a large impact on health of the population. Health is more impacted by measures that address income inequity than measures that increase overall wealth, which also increases inequality rates. Between 1980 to 1990, the wider the income distribution, the smaller the decline in morality. "If we share the resources of our country more fairly, we shall have a more cohesive society and reduce inequalities in health. It will not happen the other way around." Income equality and disability and a strong correlation at a state-level that impact the entire polulation of that state. Rich or poor, those living in states with high unequal distribution of wealth are more likely to have disabilities than those living in states with more equal distribution. Studies have proven that even the rich living in unequal states disadvantaged. A study collected from 645,000 Americans throughout the country revealed that those residing in states with high income inequality are 11% more likely to have a health issue than those living in more equal distribution ( Anon. , 2007).

A Laptop Computer

A laptop is a portable personal computer. They have furthermost of the similar components as a desktop computer, likewise a display screen, a pointing device such as a touchpad which also known as a track pads, a keyboard, and 2 speakers. Laptop computers are powered by mains electricity via an AC adapter, and can be used away from using a rechargeable battery. Sometimes there are also called notebook computers or notebooks. Laptops are portable computers. They are standard devices between students, businesspeople, and people who daily use their computer on the go.The cost of laptop is more than desktop computers for similar specifications, due to their nearby portability. They can have as extremely power and speed in place of desktops and laptop can be easily connect to external device for instance, monitors or keyboards, and other peripherals. They are more comfortable for use in business meetings, classrooms, cars, planes, trains, etc. Moreover, Laptops are that you can take all o ver the place with you without any difficulty.It can take up very small space and people can only use for few hours without access to power. Laptop computers come in many sizes, which generally refer to the size of the display. They can choice from a 10-inch to 20-inch for normal laptops. Laptops come in several resolutions ranging from 1280Ãâ€"800 to 1920Ãâ€"1080. Laptop video cards and processors are designed built on the desktop processors, but they are produced with low power in mind. They are generally less powerful than the desktop computer.Furthermore, they are increasing in popularity and for moral reason. They have benefits that are incomparable by desktop machines. And, bigger technology has dramatically dropped the price on most models. The laptop's small size removes the need for a large computer desk, and peripherals (scanners, printers, and mobile phone and external hard-drives) are simply linked with a USB cable. Wireless internet or Wi-Fi connectivity is possible, and most components now feature built-in fingerprint readers, Web cams, speakers and other operating systems.Laptop is a good technology because it very easy to take it anywhere. People can easily access to the internet and get their information by the help of Wi-Fi. Most of people are turning toward from desktop computers to laptop because its cost is decreasing, now nearby the same price as a similarly desktop computer. I really my laptop it save my time. When the electricity is gone, my laptop still on, so by the help of laptop I easily completes my assignments.

Baroque Style of Period

It's easy to play any musical instrument: all you have to do is touch the right key at the right time and the instrument will play itself. -Johann Sebastian Bach Well, yes, it's easy to play any musical instrument, but unfortunately for most, it IS hard finding the â€Å"right key' and putting your finger, or mouth, or bow on the â€Å"right time† is almost impossible. But Bach always found the right time to play, and it wasn't during the right second or on the right beat. It was the right century. 600 officially began the Baroque period, and I mention Bach because it seems this period ended tit his death in 1750. Stay tuned (all puns intended) to learn what was going on, who else had the magic touch, and the characteristics of the Baroque time. Several events took place in the one hundred and fifty year span of the Baroque period. Presumably the most influential was that the Age of Enlightenment began. That meant you had an increased chance not to be killed for being differe nt, which was great for entertainers trying to make a name for themselves.Great philosophers and writers flourished in this time, including Francis Bacon, Rene Descartes, Thomas Hobbes, John Locke, John Milton, Jonathan Swift, William Shakespeare, and John Donned. All of which high school students are forced- ERM encouraged to read about. Science was also explored, and from it, gravity- the enemy of all women standing on a scale- was discovered. Sir Isaac Newton developed laws of physics, including the Laws of Motion and, as noted above, gravity. The first opera, Eurydice, and opera house, Theater San Casino, opened in 1600 and 1637, respectively.King James Version of the Bible, the most widely distributed version today, was published and reduced in 1611, and probably the greatest moment for you and me, the pilgrims landed here in America in 1620. Go Thanksgiving! So needless to say, none of the great composers of this time came from America, and consequently, have rather difficult names for the average American to pronounce. Such as Archangel Cornell, Claudio Monteverdi, Jean-Philippe Rammer, Alexandra and Domenici Scarlatti, and Heimlich Scouts (You should see how many red squiggly lines Word has up for those).There are less complicated ones, such as Johann Sebastian Bach, George Frederic Handel, Henry Purcell, and Antonio Vivaldi. Vivaldi†¦ I love Vivaldi; his works are outstanding and seem to fit every occasion. Most commercial companies have realized this as well, regrettably, and overuse his masterpiece, The Four Seasons. Some of the other more notable works were Toccata and Fugue in D minor by Bach, The Messiah by Handel, Marcher Royals by Lully, and Coracle's trio sonatas such as Sonata for Violin and Lute.Speaking of trio sonatas, they were a popular form of the Baroque period, as were concertos, concerto grosses, suites (a set of instrumental compositions to be played in succession or a set of selected pieces from an opera or musical, arranged t o be laded as one instrumental work), oratorios, cantatas, operas, fugues (a contrapuntal composition in which a short melody or phrase is introduced by one part and successively taken up by others and developed by interweaving the parts), and toccatas (a musical composition for a keyboard instrument designed to exhibit the performer's touch and technique).While some of these forms may have been used in periods before them, the Baroque period definitively had its definitive characteristics that made it unique and created things that made it memorable. In general, the music was a bit like â€Å"how it feels to chew 5 gum†. Lying on a bed of vibrating metal balls, suspended from wires hit with a hammer, while shooting way up into the air all combined into one.The music had complicated rhythms and expansive movements; it was heavy and thick with texture, including singers and instruments in polyphonic heaven. Sounds were echoed and imitated, creating a very elaborate piece witho ut any crescendos or diminuendos to make it dynamically different. It did have dependable meters though, usually two, three, four, or six main beats. In Just a century and a half, more than two dozen people made artistic history. The Baroque period was a great time of advancement in several areas, especially music.Numerous composers, such as Bach, Handel, Scouts, Vivaldi, Cornell, and Lully, and their work, like The Messiah, and The Four Seasons, survive to this day. The Baroque area has its own defining characteristics, such as complicated rhythms, elaborate melodies, pieces thick with harmony, and syrupy textures. It was also during a time of great change and many new discoveries, such as gravity, the first opera and opera house, and the beginning of the Age of Enlightenment. Hopefully this essay did some justice to the Baroque era. That's all folks.
